How We Chose The Best Online Slot Sites

Are you wondering how we came about our list of best slots sites in the UK? Below is a lowdown of all the factors our team considered in ranking the top UK online slots and picking the best of the best. 

  1. Slot Collections

The first thing we consider when choosing the top online slots is the variety of games in their cabinet. The best slot sites offer their players numerous options, including classic slots, full-fledged animated slots, movie-themed slots, mega ways, and high-reward jackpot titles. All the best slots sites we listed have thousands of titles you can play for real money. Another factor we consider here is how often the casinos update their slot lobby. We only picked online slots that add new titles to their cabinets from time to time. 

  1. Slot Bonuses

We know all slot fans love bonuses. So we didn’t just focus on casinos with huge bonuses; we examined the bonuses further to ensure they would appeal to fans. We prioritize slot sites that offer players generous free spins as part of their welcome bonus and ongoing promotions. So when you pick a casino from our list, you are sure to enjoy hundreds of free spins and some cash bonuses to play your favourite online slot games. 

  1. Software Suppliers

Our experts know that the best slot titles are from the world’s most reputable providers, so we consider this when ranking casino sites. Before making our picks, we check the supplier of each casino’s games. Those with games from unknown providers are crossed out, and sites with top names like NetEnt, Microgaming, Red Tiger, etc., are considered in our list. 

  1. Security and Licensing

Licensing is one of the most important factors to us when ranking casinos. We don’t want our highly esteemed readers playing at unlicensed online slots. So we go the extra mile to make sure that only casinos licensed and regulated by the top institutions in the UK make it to our best online casinos list. In addition, we examine the features each site has in place to prevent data theft or intrusion by hackers. 

  1. Payment Methods

Gone are the days you have to stick to one or two banking options when playing at a casino. Today, top online slot sites support over ten payment methods with fast transaction processing time. All the casino sites we listed support payments and withdrawals via debit cards, bank transfers, and e-wallets, such as PayPal, Neteller, and Skrill. In addition, the sites process withdrawals and deposits almost instantly. 

How To Get Started On UK’s Best Slots Sites

Are you ready to start playing online slots for a chance to win real money or maybe win a life-changing jackpot? Follow the simple steps below to get started.

  • Pick from our list of best slots

Our casino experts have helped you narrow down the best of the best online slots, so you don’t have to go through the stress of vetting each slot site yourself. We recommend starting with two or three casinos so you can compare gameplay and other features to determine your best option. 

  • Register on the slot site

Once you pick your preferred online slot sites, the next step is to create an account at the casinos. Most online slots require you to provide a username, email address, and password to register. This process usually takes less than five minutes.

  • Make your first deposit

If you are hoping to get a welcome bonus from the casino, you must check the minimum required deposit to qualify for this bonus before making your first payment. Most casino sites require their players to deposit between £10 – £30 to become eligible for their welcome bonus. 

  • Start Spinning

You can start spinning the reels of your favourite slot machines once the casino confirms your deposit. Also, if you earned free spins as part of your welcome bonus, you can use it to play for free for a chance to win real money before playing with the funds you deposited. 

Best Games To Play On Slots Sites

As a beginner in the slot world, you are likely wondering which slot titles will get your juices flowing and offer you the best chances of winning. We have combed the best online slots sites to bring you the best titles to try first. We are sure all the games on our list will give you an adrenaline rush.

  • Starburst

The first title on our list of best games to play on UK slots sites is Starburst. Though launched about a decade ago, the game has maintained its position as one of the top slot games online. Most online slots target their free spins bonus on this title, so you must acquaint yourself with this game if you love to claim these bonuses. Starburst is a low volatile game with 96.08% RTP. Hence, players win more frequently in this game than in other high or medium volatile slots. 

  • Book of Dead

Another top game we recommend on slot sites is Book of Dead. Play’n Go launched this ancient Egypt-themed game about five years ago and has grown to become the favourite slot for several casino players. Book of Dead comes with free spins and several other bonus features to make winning easier for you. Like Starburst, Book of Dead also comes with a decent RTP, making it a suitable game for beginners. 

  • Gonzo’s Quest

Follow Gonzalo Pizarro on his quest to explore El Dorado, a city known for its several mythical treasures. Gonzo’s Quest stands out for its beautiful 3D graphics and multiple features, such as free spins, bonus rounds, great storylines, etc., that will keep you entertained for a long period. Gonzo’s quest is a high volatile game, so the frequency of wins is lower. However, when you win, you will have something big to take to your bank. 

  • Big Bass Bonanza

Big Bass Bonanza is a 5-reel, 10-payline slot title launched by Pragmatic Play some years ago. This action-loaded game is simple and fun to play. Aside from being an entertaining game, our online slots experts like Big Bass Bonanza because it comes with several features you can leverage to unlock multiple free games. For example, the RTP of Big Bass Bonanza is 96.71%, and you can win as high as 2,100x of your stake. 

  • Wolf Gold

Our list of the best games of slots won’t be complete without a mention of wolf Gold, a visually-stunning game set in the heart of a desert. Pragmatic Play loaded this 5-reel slot game with many bonus features, including mini, major, and mega prizes. When you play Wolf Gold, you have a chance of winning up to 250,000coins. This slot title is a medium volatile game. It is perfect for slot players trying jackpot slots for the first time. 

Types Of Online Slots Every Player Should Know

Now that you know the best slots sites, how to start playing slots online, and the top games to play, the next step is familiarizing yourself with the various types of online slots. This will help you decide on which games to play. Below are the different types of slots you should know. 

  • Classic Slots

Classic slots, sometimes called 3-reel slots or one-armed bandits, are the simplest types of online slots to play. These slot machines come with three reels and have one to three paylines. However, modern classic slots now feature up to ten paylines, arranged horizontally, vertically, and diagonally on the machine. Classic slots are ideal for newbies as they are easy to learn and play. Trying classic slots is a perfect place to start if you are a first-timer looking to play simple, low-variance slots.

  • Video Slots

Video slots, also known as five-reel slots, are advancements of classic slots. They are digital, so they do not come with mechanical reels. All you need to spin on a five-reel slot is to press a button. Video slots come with alluring graphics and soundtracks designed to attract players and keep them entertained. These slot machines have more pay lines, so you will likely win more when playing video slots than classic. 

  • 6 & 7 Reel slots

Aside from the popular classic slots and video slots, other slot machines gaining popularity among UK players are the 6 & 7 reel slots. These slots go beyond the conventional structures to create 3×6 and 7×3 setups. They come with more reels and are packed with almost all the features you get on a five-reel slot, making them an exciting game to try. 

  • Progressive slots

Progressive slots, also called progressive jackpots, are casino games with payouts that increase each time someone plays the game and the prize isn’t won. In other words, each player playing a progressive slot contributes to the jackpot until the prize is won. Sometimes the jackpot could go into hundreds of thousands or millions before it is won. However, the main drawback with this is that you must place the maximum wager to qualify for the game. 

  • Virtual Reality slots

Virtual Reality (VR) technology has also made its way into the online gaming industry. Today, numerous VR slots are riding on technology from brands like Oculus Rift, Sony Play Station, Razer OSVR, etc. Virtual Reality slots offer an immersive and realistic experience similar to what you get at brick-and-mortar casinos.

Common Symbols On Online Slots Machines

There are various types of symbols you will encounter when playing. These symbols are part of the gameplay, and you must understand them to have a great gaming experience. These sections will break down the meaning of some of the common slot machine symbols. 

  • Original slot machine symbols 

The first set of slot machines came with playing card symbols – diamonds, spades, hearts, Queen, King, Jack, and Ace. Later, the traditional lucky symbols, Liberty Bell and Horseshoe, were added to slot machines. These symbols are evergreen as they are still very common in today’s slot machines. 

  • Fruit symbols

Whatever games you choose, you will see many slot machines with fruit symbols like grapes, cherries, apples and lemons. Before the advent of fruit symbols, slot machines had only numbers, and they paid out coins. However, due to legal restrictions, some manufacturers replaced card numbers and suits with fruit symbols and made machines that dispense chewing gums of different flavours instead of cash. This is how fruit symbols found their way into the slot world. 

  • Lucky number 7

Another common number on slot machines is the lucky number 7. These number is visible on almost all slot machines worldwide. It is believed that it is widely used because most cultures and religions associate the number with good luck and fortune.

Types Of Slot Symbols

Aside from the common symbols on slot machines, another important thing you should know before playing at UK’s best casino sites is the types of symbols. There are several categories of slot symbols; however, the most essentials are:

  • Standard symbols

Standard symbols are the regular symbols, such as fruit symbols or card numbers, that don’t have a special function on slot machines other than to form a winning combination. 

  • Wild symbols

These are symbols that serve several functions, including replacing another symbol on the slot machine. In other words, you can use a wild symbol to substitute another symbol to form a winning combination. 

  • Scatter symbols

Scatter symbols help you activate the slot’s machine in-game incentives like free spins and bonus rounds. When you land scatter symbols, you could get bonuses to extend your playtime and increase your chances of leaving the casino with a profit. 

  • Bonus symbols

Bonus symbols are similar to scatter symbols; they help unlock bonus rounds. However, the difference between the two is that bonus symbols must land on specific lines before they can be activated. 

  • Multiplier symbols

Multipliers are the easiest symbols to understand. They do what their name implies – multiply your wins. When you land a multiplier, they can increase your payout up to six times. 

Pros Of Playing Online Slots

Below are some reasons why new and experienced gamblers are switching from land-based slots to online slots. These factors can also help you decide if playing online slots is your best option.

  • More array of games

There is a wider variety of slot games online than in physical casinos. Some online slot sites have over a thousand titles. So when you play online slots, there is no shortage of choices.

  • Easy access

Gone are the days when you have to leave the comfort of your home to play your favourite slots. Online slots have made it possible to play any game you want anytime and anywhere using your computer or smartphone.

  • Better rewards and incentives

Online slots come with bigger bonuses and incentives for new and regular players. For example, when you register on the best online slots we recommended, you get 100 – 300 free spins to use on some of their top games.

  • Higher payouts

Online slot sites have lower overhead costs than land-based casinos, so you can expect a higher payout when you play online.

  • Multiple banking options

Unlike physical casinos, where your banking methods are limited, online casinos offer their players more options. For instance, you can deposit funds or withdraw your winning from most casino sites using debit cards, bank transfers or electronic wallets such as PayPal, Skrill, or Neteller.
